Great thread, I enjoyed reading it.
Of course it is, because nicotine has very little to do with the smoking/vaping habit except for acting as a discriminative stimulus to tell the brain you are getting nicotine. Nicotine is not the terminal reinforcer in the chain of responses making up smoking/vaping behavior. Having completed the chain is the terminal reinforcer. This is why smoking is such a difficult habit for some people to quit. It is the behavioral act of smoking/vaping that is habitual. Using more mls is directly a consequence of engaging in vaping behavior more. This accounts for why many people who successfully substitute vaping for smoking find it relatively easy to reduce their nicotine intake to physiologically meaningless concentrations with little to no effort. If nicotine was maintaining the response, these people would not continue to vape. That they do demonstrates conclusively that nicotine is not reinforcing the response chain involved in vaping behavior. Viewed from that perspective, I am a much better candidate for psychological addiction to nicotine than is either a long time smoker or somebody who substitutes vaping for a long ingrained smoking habit. Assuming that I haven't been experiencing a placebo effect for the last year and a half I have been vaping and obtaining a positive pharmacological effect from the nicotine, reducing my nicotine intake will directly lead to negative consequences (i.e., negative punishment). My guess is that if this cognitive enhancement I am experiencing is a real effect, the longer I continue to vape the larger the contrast will be if I stop ingesting nicotine. Since it is the nicotine that my improved cognitive clarity is dependent on, I should find it reasonably easy to change my route of administration if, say, the university passes a proposed draconian "campus-wide nicotine products ban" that would make possession of any nicotine product not recognized by the medical establishment as a valid smoking cessation tool illegal on campus. If that happens, I guess I am forced to dose myself orally with nicotine lozenges. Except for working out pharmacodynamic equivalence in the routes of administration that fits my own physiology, I shouldn't have a problem with this, except I hate the taste of those things.
The research is being done, but nobody in the media cares....

True that dav and I'm a beneficiary for one.
Good luck all and Merry Christmas.
I haven't taught my neuropharmacology course for a couple years and I'm currently teaching it this semester. I'm giving the alcohol & nicotine lecture next week and I will post the nicotine part of the PowerPoint lecture if there is any interest. I think that PowerPoint allows export to a PDF so people won't need PP to read it.

Mosspa, perhaps you can expand on this and correct me if I am wrong, but I think this is because of an upregulation in the nicotine-binding receptors in the brain to compensate for their saturation.
This might also be the reason for which some people start feeling like they need nicotine to function normally after sustained long-term usage, and perform at below-baseline levels when withdrawing from nicotine.
Count me in as well, @mosspa . If ECF doesn't allow posting a pdf, maybe put it up on your blog page?
Thanks for checking in with us. We are eager students. If so much more is known, presumably mostly good news, how come none of that seems too be filtering into the debate about ecigs? Public health officials and government regulators say stupid things about nicotine that scientists probably knew weren't true 30+ years ago.I'm kind of ashamed to admit my failure to keep up with the advances in the pharmacodynamics neuropharmacology of nicotine in favor of a selfish interest in the pharmacokinetics (absorption and distribution, mainly). An amazing amount of information about the brain nicotinic acetylcholine (nACh) systems has been garnered since the last time I comprehensively reviewed the pharmacodynamics literature. While both up regulation and down regulation phenomena occur with brain nACh receptors, the receptors themselves are self-modifying in their responses to nicotine. The two main aspects that account for much cognitive and neurobehavioral phenomena are (1) the propensity for high concentrations of nicotine to act as antagonists at most nicotinic receptors, and (2) for the receptors to be come desensitized to nicotine shortly after their initial activation by the drug. Additionally, in the last eight years, or so, a lot has been learned about the specific location and function of many different sub-types of brain nicotinic receptors. By integrating all of this rather new knowledge, it is now possible to form better hypotheses as to how nicotine works to produce the effects that are observed. This, however, would be too much information for a single post here (especially one I constructed off the top of my head). I have been working on a total reorganization of the nicotine lecture for over a week, now, to get all of this information in one place. After I post the PowerPoint some of your questions may be answered, or at least you will have some information on which to ask more specific questions.
I'm pretty sure I posted at least one PDF to this thread. I know the software on which this forum is based accepts them, so I'm pretty confident it will work. Also, I don't have a "blog page" of which I am aware. If worse comes to worse, I can always upload it to MediaFire and hot link that here.
